3. Executive Summary
Not only is Napa County home to a major share of California’s wine heritage as well as many of its most
admired wines, the county also accounts for a significant share of California’s wine industry.
1
In 2011, Napa County, including both Napa Valley appellation wines and wines produced in Napa County
from grapes from other regions, produced about 20% of all the wines produced in California and between 16%
2
and 17.5% of all the wine produced in the United States, according to data provided by the Alcohol and
Tobacco Tax and Trade Bureau of the US Treasury Department.
Sales of wine produced in the county account for 52% of the total retail value of all the California wine sold in
2011 and 26.6% of the volume of all such wines.
This scale of wine activities in the county is reflected in its economic impact. In 2011 Napa’s wine industry had
a total economic impact of more than $13 billion on Napa County’s economy, $26 billion on the California
economy, and $50 billion on the American economy, as detailed in Table 7 below.
This second update of the economic impact of Napa County wine and grapes is distinguished from the
previous studies by:
 The inclusion of estimates for all the wine produced in Napa County, not just Napa Valley appellation
wines, thanks to the generous cooperation of some of Napa’s major producers.
 More thorough consideration of the suppliers and service providers to the industry, as discussed
below.
A Note on the Data
Each time we do these studies we need to stress that there is hardly any public or standardized data on this
complex industry. The State of California Department of Forestry and Agriculture, through its division of the
National Agricultural Statistics services (NASS), provides substantial and detailed data on grape production,
acreage, and sales, down to the district level -- and fortunately Napa is a single district. Wine sales volumes
can be deduced from Federal and state excise tax data, although such data is not available for entities below
the state level. National and state level wine production numbers and wine sales volume indicators (wine
removed from bond) are published by the TTB and county level detail can be obtained on request. Winery
numbers can be obtained from both state (California ABC) and Federal sources (TTB) -but these numbers
seldom agree, due to timing differences in permit approvals and cancellations and different license categories
at state and federal level.

For this report, wine produced in Napa County includes wine blended, bottled or grown within
NapaCounty.
2
Napa county wines accounted for 17.5% of all wines bottled in the US in 2011 and 16.1% of all wines
fermented in the US in 2011, according to TTB data. TTB defines “production” as fermenting, with bottlingas a
separate activity. Napa County bottles somewhat more wine that it ferments, as some largeproducers
centralize their bottling activities from adjacent regions in the county.
Stonebridge Research: Economic Impact of Napa County’s Wine and Grapes, 2011 Page 3 of 19

4. No region can provide specific vineyard counts, as vineyards are often held in multiple parcels for private
tax reasons. Employment and wage data by county is available for certain industry categories from the US
Department of Labor Bureau of Labor Statistics. Fortunately, wineries and vineyards are specific
categories for such data -- but most supplier industries and services (e.g. cooperages, bottles, closures,
capsules, tanks for wine, wine laboratories) are buried in broader categories such as “glass containers” or
“wood processing.” Moreover, even for specified categories, these data only cover employees eligible for
unemployment insurance, thus excluding owner-operators, contract and part-time workers. Revenue data
is not available from any published source.
Thus, these studies depend on diligent primary research: multiple industry interviews combined with
searches of multiple sources for pieces of information that can be assembled to substantiate an estimate.
To provide a metric for the effort, we tracked employment, revenues, and wages for approximately 72
industry activities for this study, with about 200 phone calls, emails, and meetings in addition to more
conventional data and document searches. Much of this process is explained below but please understand
that these findings are best available estimates.
Wine Produced in Napa County
Many of the wineries established in Napa County prior to 1990, including some of the major wineries in the
US, traditionally produced wine from grapes grown in the Napa Valley (wine entitled to carry the Napa
Valley appellation and the various Napa Valley sub-appellations) as well as from grapes grown in other
regions of California, making all of their wines, in all price ranges, within the county. The passage of the
Winery Definition Ordinance (WDO) in 1990 required wines produced in wineries developed after that date
to have at least 75% Napa grapes. The WDO is considered a cornerstone protection of Napa’s Agricultural
Preserve and the agricultural character of the county.
The scale achieved by these major producers, along with the quality reputation of Napa Valley wines,
attracted many suppliers and service providers to Napa County, including bottling, processing, and storage
facilities in the southern part of Napa County. This cluster of industry expertise attracted still further
vintners, winegrowers, and service providers to the county, making Napa a key center of the California
wine industry.
The Alcohol and Tobacco Tax and Trade Bureau (TTB) provided, in response to a special request by the
Napa Valley Vintners, the following data on total volume of wine produced and bottled in Napa County for
2010 and 2011 and the total volume of tax-paid wine removed from bond in Napa County for the same
periods. Tax-paid wine removed from bond is a reasonable indicator of wine sales by Napa producers
(although it excludes exports, which are not subject to excise tax.)

5. In both 2010 and 2011, wine removed from bond exceeded estimated production, most likely because
wine was sold out of inventories, which had grown as sales of more expensive wine fell with the onset of
the recession in late 2008 through 2009.
Based on these data, and further data published by TTB on California and US wine produced and bottled,
we have estimated that Napa County wines account for one in five bottles of wine produced in
California while Napa Valley appellation wines account for 3% of such wines. The TTB does not track wine
production by AVA. Production volumes for Napa Valley wines have been estimated from grape production
data and industry interviews.

The total retail value of all the wine produced3 in Napa County, including sales through the 3 tier system as
well as direct to consumer and export sales, is estimated to have totaled $10.1 billion in 2011, with the
retail value of Napa Valley appellation wines estimated at $5.5 billion, or 55% of the value of county’s wine
sold while only 15.6% of the volume of the county’s wines.

The Wine Institute estimates that California wine accounted for 61% of the volume (and value) of the wine
sold in the US in 2011, estimating total California wine sales volume at 211.9 million cases and the total
value of sales of California wine at $19.9 billion.

Thus, as shown in Tables 2 and 3 above, wine produced in Napa County, representing 17.5% of the all
wine produced in the US, accounted for 31% of the value of all the wine sold in the US in 2011, or about
one out of every three dollars spent on wine sold in the US. Napa Valley appellation wine alone
accounts for almost 17% of the value of all sales of wine in the US, from only 3% of total US wine
production.
The retail value of wine produced in Napa County accounts for 50.8% of the value of all California wine
sold in the US in 2011. Napa Valley appellation wines, representing many of the highest value wines
produced in California, alone represent 27% of the total value of all California wine sold.

7. Consumer Direct Sales
The California State Board of Equalization (BOE), which collects California State sales and use tax, as well
as fuel, alcohol, and tobacco taxes and fees, has now started reporting sales tax collection by type of
industry collecting the tax. Responding to a special request for this study, the BOE was able to provide
sales tax collections directly by wineries and the totals for related taxable transactions. Sales taxes are
collected on taxable retail sales and thus these amounts can be reasonably assumed to reflect total retail
sales by wineries, principally wines sold directly to consumers, picked up at the wineries or shipped within
the state of California.
Industry interviews allow us to estimate the share of such taxable transactions in total consumer direct
sales and thus the total consumer direct sales for wineries in Napa County. On this basis, total consumer
direct sales for wineries in Napa County are estimated to total $745 million.
Assuming that Napa Valley appellation wines represent the greater share of consumer direct sales, as
consumers seldom buy direct from a winery those wines which they can easily purchase at their local
retailers 4, consumer direct represents more than 30% of sales revenue from 15.4% of case volume for this
segment of production. Since Napa Valley appellation wines tend to be the highest value wines produced
in the county, consumer direct is estimated to represent nearly 17% of total winery revenue in the county,
from only 2.4% of total county case production5.
The BOE data indicates that retail sales by wineries in Napa County represent 38% of all retail sales by
wineries in the State of California.

Region Taxable Transactions

Employment
Wineries employ full and part-time workers as labor for bottling, storage, maintenance, and winemaking
needs as well as hospitality, finance, sales, and marketing functions. Some wineries also employ seasonal
labor, for both harvesting and hospitality. Vineyard employment-vineyard management, contract labor and
self managed. A very high proportion of Napa’s vineyard labor are locally-based, full time employees.
Supplier employment is more complex, as discussed below.
Napa Valley grapes, Napa County wine and their allied industries, directly and indirectly, provided full-time
equivalent jobs for more than 46,000 individuals in Napa County, for total of nearly 102,000 individuals
4Most of the non-appellation wines produced at Napa’s larger wineries do have such national retail
distribution.
5 This large share of revenue relative to production results from the concentration of direct sales in the
higher value appellation wines. Few consumers would ship wines which are generally available at their
local retailers, as are most of the non-appellation wines produced by the county’s larger wineries.

8. across the state of California and for about 303,0006 workers across the US. The Napa wine and grape
industry, with related activities, accounts for more than two-thirds of all the full time jobs reported in the
county in May 2012.

Tourism
We estimate the total number of visits 7 to wineries at 3.8 million in 2011, based on interviews with a large
cross section of wineries in each of the major sub-regions of the county as well as the winery
benchmarking studies we have conducted over several years. The interviews included wineries open to
visitors, appointment-only wineries and wineries not open to the public. Wineries have quite varied
methods of tracking their visitor numbers -- paid tastings, glasses used, CRM or POS entries, etc. -- and
some are still developing their visitor tracking methods.
6We know that wineries employ numerous personnel, particularly in sales, across the US, including in
other regions of California, but were not able to include a reliable estimate for such labor in this study.
7 Note also that the number of visits is not the same as the total number of visitors to the county, as
visitors often visit more than one winery.
Stonebridge Research: Economic Impact of Napa County’s Wine and Grapes, 2011! Page 8 of 19

9. We then use all the information collected to estimate visitor numbers for each of the licensed wineries in
the county, double checking our estimates with multiple wineries. In these estimates as in all estimates
developed from interviews for this study, we always take the low end of a possible range of values to
ensure that estimates are conservative as well as realistic.
The total number of visits to Napa Valley wineries has recovered to somewhat above its pre-recession
levels, based on interviews with a large cross section of Napa Valley’s wineries, although visits seem
concentrated among wineries with stronger followings and brands.
Our next step was to determine the wine tourism related spending and employment in the county. This
proved difficult this year, given the limitations of the data available on overall tourism patterns for the
county and state. The Purdue University study of Napa Tourism, commissioned by the Napa Convention
and Visitors Bureau in 2005, included a broad consumer intercept which allowed them to estimate that
more than 77% of Napa Valley visitors visited at least one winery. We feared that this study was outdated.
Finding comparable current data proved challenging.
In past years, annual studies commissioned and published by the state travel organization (formerly
California Travel and Tourism, CTTC, now called Visit California) provided estimates total visitors, and total
tourism employment and spending by county. However, due to budget cutbacks, Visit California’s latest
studies cover only 2009 and do not provide total visitor estimates by county, although it does estimate
county tourism spending and employment. Visit California staff suggested using a metric of $400
spending per visitor to estimate visitor numbers. Unfortunately, this number of visitors thus derived
(dividing estimated total tourism spending by $400) suggests a much smaller number of visitors than other
data (TOT collections, etc.) would suggest. Moreover, the $400 per visitor estimate seems quite high, given
the large share of day trips by Napa Valley’s visitors.
To resolve these issues conservatively, Stonebridge reverted to Purdue’s 2005 estimate of 77% of Napa
Valley visitors visiting wineries plus the 2009 Visit California estimate8 for total tourism-related employment
and spending in Napa in order to develop estimates for the total spending and employment in the county
attributable to winery visits. We realize these are not perfect numbers but the best that can be obtained
given the information available.
The overall impact of Napa Valley winery visits on tourism would benefit from still further investigation. Visit
Napa Valley, the Napa tourism agency, is working on visitor count estimates, although these may only be
based on hotel stays, leaving questions about day visitor numbers still unanswered. Other questions merit
examination. For example, San Francisco continues to estimate that 23% of its visitors visit “wine
country.” However, there is no data as yet to assess the extent to which “wine country,” and specifically
Napa Valley, as a world recognized destination, also brings visitors to San Francisco. Hopefully, future
research planned by Visit Napa Valley will consider these issues.
8The Visit California study used national metrics developed by the US Bureau of Economic Analysis to
determine the employment breakdown by sector. However, this metric does not really fit Napa County. For
example, the metric assumes more employment in the “recreation” sector than the California State
Department of Employment Development reports existing in Napa. It also is not clear where wineries
belong in this sector breakdown.

10. Suppliers and Service Providers
Each iteration of this study allows more opportunities to deepen and expand the analysis of suppliers and
service providers to the industry. Since the enterprises involved in the industry are either privately owned or
services to the wine industry are just one of several lines of business for the enterprises, there is little if any
public information available. Individual interviews with a combination of suppliers, vintners, growers and
industry advisors are required to assemble the relevant data. Since the information collected is often
proprietary, we have aggregated the data presented into broad categories. We are most grateful for the
cooperation and patience of so many of the respondents.
The research indicates some interesting trends among suppliers and service providers:
• An increasing proportion of the finishing work for both barrels and corks is conducted locally,
primarily in Napa, although most of the raw materials for both are imported.
• Purchase of new oak barrels has declined considerably, by 30% to 50%, with increasingly
sophisticated use of barrel alternatives and growth of stainless steel fermentation.
• Glass bottles for Napa County’s wines are largely produced within California. We had
previously assumed that much of this production occurred in various other regions of the US.
Imports are a relatively small share of the bottles used for Napa County wine out of concerns
about consistent quality. To some extent, Chinese imports are taking some market share from
bottles produced in Mexico.
• Much of the equipment used in wine production is quite specialized and much of this
equipment is produced in Europe. Sales representatives and distributors for these imports
tend to be based in Napa Valley, and serve the rest of the US winemaking industry from Napa
Valley. Other highly skilled wine related activities, such as laboratory testing, serve the rest of
the country from a Napa Valley home.
• Napa County suppliers tend to be distributors, retailers and service providers. The
manufactured products used by wineries and vineyards are more likely to be manufactured
elsewhere, often neighboring counties, for which Napa County provides much of the market.
• However, Napa County is home to most of the high-value added cork and barrel finishing, and
much of the label production for the industry. Construction, custom metal work, and similar
activities for Napa wineries are also more likely to originate in Napa but stainless steel tank
construction has largely shifted to neighboring counties.
• The inclusion of the large volume of non-appellation wine produced in Napa County
highlighted the degree to which wineries have outsourced wine-related freight and storage to
independent companies. From grape hauling, bulk wine, and case goods shipment to bulk
wine, barrel, and case goods storage, highly specialized warehousing and freight services are
major activities in the industry and in Napa County’s economy. Many of the freight companies
in particular are small, local entrepreneurial firms.
Stonebridge Research: Economic Impact of Napa County’s Wine and Grapes, 2011! Page 10 of 19

11. • Many of the vineyard workers in Napa Valley today, whether working for wineries, vineyards, or
vineyard managers, appear to be full time, and long term, employees, often receiving full
employee benefits.
Public Revenues
From grape to consumer, the wine and wine grape industry generates significant tax dollars, benefiting
federal, state and local governments. Tax dollars are raised through sales taxes, excise taxes, income
taxes, estate and gift taxes, payroll taxes, property taxes, and other business taxes and fees, including
permits and licenses of various types.
Activities in Napa County related to wine produced in Napa County generated nearly $1.3 billion 9 in total
public revenues in 2011, including more than $660 million in state and local taxes 10 and other public
revenues and more than $621 million in Federal revenues. Activities within California related to wine
produced in Napa County generated nearly $2.4 billion in public revenues at the state, local, and federal
levels. Across the US, these activities generated nearly $5.2 billion in public revenues at all levels.
In addition to Napa County’s share of various general state and local tax revenues, Napa County
directly received more than $50 million in taxes and assessments from wineries and growers and
related industries in 2011.
The Napa County Assessor estimates that: “the wine industry, including vineyards, wineries, warehousing,
corks and capsules, coopers etc., represents approximately 12-18% of the county’s assessed value or
$3.25 billion to $4.86 billion in assessed value. That assessed value would generate between
approximately $35.4 billion and $52.9 million in annual property taxes.” We assume a midpoint in these
amounts in the table below.

9 All the tax estimates in this table, except for the county specific estimates, excise and winery direct sales
taxes, were produced by the IMPLAN model, explained on page 15 below, based on the employment
data provided by Stonebridge.
10Included in this total are $866 million in California state and local indirect taxes, as calculated by the
IMPLAN model. IMPLAN includes in this total of state and local indirect business taxes: $379 million in
sales and use taxes, $413.4 million in business property taxes, $8.6 million in motor vehicle taxes, and
$38.3 million in severance tax, 'other' and non-taxes (e.g. fees etc.). Some of these taxes (e.g. property,
some parts of sales taxes) are collected at the local government level. The latest revenue update for the
California budget identifies $18.8 billion in sales tax collections, and $6.1 billion in “other and insurance
taxes”, for a total of nearly $25 billion. Thus, the total for state level 'indirect business' taxes attributed to
Napa wine is about 1.5% of total state level indirect business taxes.

13. Charitable Contributions
The wine industry is unique in its charitable support to the community. Based on discussions with the
industry, charitable contributions in 2011 are estimated at nearly $84 million in-kind and in-cash, plus
substantial donations, generally in-kind (wine for auctions and related travel) or sponsorships, for charities
in the rest of the country.
Many wineries do not even track such contributions or differentiate between family and company support.
To estimate charitable contributions in 2007, we conducted industry interviews and winery surveys and
concluded that the industry’s contributions tended to average about 1.7% of winery revenues 11. As the
recession has deepened, and other sources of funding have declined, industry interviews have indicated
that the industry has increased this support of community services. Consequently, we have increased our
estimate of such support to about 1.85% of revenues.
We have not attempted to estimate the many charitable donations provided by Napa Valley’s wine industry
to activities outside the county.
Napa’s wine industry has long provided critical support to sustain Napa County’s social safety net. Napa
Valley’s wine industry is particularly notable for the scale of support it provides to education, health, and
social services in the county. In 1999, long before neighboring counties even considered such programs,
Napa Valley Vintners established the Napa Valley Vintners Community Health Center. The Center houses
Clinic Olé, now in its 40th year, which serves low income and uninsured individuals. Additionally, the Napa
Valley wine industry taxes itself to provide quality housing for farm workers.

15. Methodology
The best way to understand an economic impact analysis is to see it as the answer to the question: what
would we lose if this industry disappeared tomorrow? Intuitively, we all know that the answer to that
question is far more than the industry’s direct sales. It is more than any other element all the jobs and the
tax revenues lost; the business for the restaurant where the workers ate lunch and the car dealers who
sold them cars; the office supply stores where the companies bought printers and papers, and the sales
and business and other taxes paid by all those businesses. An economic impact study is essentially a way
to put numbers to those losses.
To produce this assessment, Stonebridge Research Group LLC explored and developed metrics for the
multiple components of this very complex industry: from wine grape growing and winemaking to the many
allied industries involved in wine production and consumption, grape cultivation and allied industries -
distribution, tourism, equipment, and suppliers. Other economic benefits, including tax revenues, financing,
charitable contributions and other indirect and induced benefits generated by the wine industry are also
summarized.
This report is an update of the 2008 study and is based primarily on 2011 data, although 2010 data was
included for some data items where 2011 data was unavailable (primarily tax and some tourism data.)
In some areas, data sources available to us have changed or been somewhat revised. In certain other
areas, we have been able to improve substantially the accuracy of the analysis, such as the supplier impact
calculations. Expanding the scope of wine production to include all wine produced in Napa County, not
solely Napa Valley appellation wine, makes it somewhat difficult to compare this report with the previous
reports so that readers may assess the progress of the industry. However, this expansion also makes the
study far more accurate and relevant; we had been including all winery employment but not capturing all of
their output since the many employees may be involved with production of wine from both appellation and
non-appellation grapes, depending on their role.
Direct, Indirect and Induced Effects (IMPLAN)
Much like dropping a rock into a pond, the wine industry has ripple effects on the Napa County, California
and US economies. Economic impact studies estimate the impact of an industry in a defined geographical
area by identifying and measuring specific concrete economic “events.” The events tracked in this report
are jobs by industry code.
IMPLAN is the acronym for “IMpact analysis for PLANing.” IMPLAN is a well established and widely used
economic model that uses input-output analyses and tables for over 500 industries to estimate regional
and industry-specific economic impacts of a specific industry.
Thus, the full economic impact of wine produced in Napa County wine, as shown in Table 6, combines the
Napa County wine industry’s direct, indirect, and induced economic effects as measured by the
application of the IMPLAN model to the employment data presented in Table 4 of this report.
The IMPLAN model and its structure are updated annually to reflect changes in the US economy, in wages,
in productivity assumptions, and in regional economic structures. Thus, readers should not try to directly
compare the IMPLAN results from the previous reports with the results of this update.
Stonebridge Research: Economic Impact of Napa County’s Wine and Grapes, 2011! Page 15 of 19

16. The IMPLAN model and methodology classifies these effects into three categories, as defined below:
Direct Effects, Indirect Effects, and Induced Effects.
Direct Effects
Direct effects are economic changes in industries directly associated with the product’s final demand.
Thus, direct effects in this case consider the direct employment and spending of wineries, vineyards,
distributors, and immediately allied industries, data on which Stonebridge Research Group LLC collected
through primary research.
Indirect Effects
Indirect effects are economic changes - income created through job creation - in industries that supply
goods and services to the directly affected industries noted above. Examples of industry effects are
purchases of electricity and gasoline by wineries or of janitorial services by wine bottle manufacturers.
These may also be defined as “secondary economic exchanges.”
Induced Effects
Induced effects are the effects of these new workers spending their new incomes, creating a still further
flow of income in their communities and a flow of new jobs and services.
Examples are spending in grocery and retail stores, medical offices, insurance companies, internet
providers, and other non-wine related industries by workers in industries allied to the wine industry - such
as the spending by the janitor working under contract to the wine industry supplier. These tertiary
exchanges induce more jobs and incomes throughout the state and the nation, based on the original
economic flows from the Napa County wine industry.
Taxes
The IMPLAN model estimates all non-industry-specific taxes generated at federal, state, and local levels by
the jobs produced by the industry in the respective geographical area. Stonebridge added to these
estimates industry specific taxes including federal and state alcohol excise taxes, consumer direct sales
taxes, and assessments paid by the industry, because these amounts are not included in the IMPLAN
results.
Measuring the Full Economic Impact of Napa County Wine and Grape Production
Napa County’s wine industry has a “multiplier” effect, extending across a broad network of economic
benefits. The revenue derived by the wine industry becomes income for other workers and firms, in Napa
County, in California, and across the US, who spend more money on other goods and services.

17. APPENDIX: COMPARISON WITH 2008 IMPACT REPORT
The 2008 report considered only grapes produced in Napa Valley and wine produced from those grapes
(generally, Napa Valley appellation wine) and was based on 2006 data. The 2008 approach was largely
dictated by the available data - data on wine in Napa County produced from non-Napa Valley grapes was
not available.
This year several of the wineries processing non-Napa Valley grapes kindly cooperated in providing the
data needed to allow the study to consider all aspects of Napa County’s wine industry. Thus, the 2011
report considers all wine produced/processed/blended and bottled in Napa County-- which actually
accounts for the major share of the industry’s economic impact.
Some points to note:
The Updating Process for Economic Impact Studies
Each update of these studies provides an opportunity to delve more deeply into the economics and
structure of the industry, especially the many allied industries, from cooperages, corks, and closures to
transport, warehousing, and construction.
Moreover, many of these industries have changed over the period. For example, the industry has reduced
its use of new barrels and increased its use of barrel substitutes while also shifting much of the finishing
work for both barrels and corks from overseas suppliers of the raw materials to processing facilities in
California. In addition, several suppliers which had been Napa County based have moved at least part of
their operations to Sonoma County to reduce costs.
The expanded grape processing volume led to substantial increases in estimates of total supplier and
professional services employment, revenue, and wages, as well as tax impacts.
The 2008 report assumed, in the absence of better data, that any wine-related employment found in Napa
or for Napa wineries was related to Napa wine as then defined, i.e., Napa Valley appellation wine.
It is clear today that a large share of the related industry employment, wages, and revenues identified in the
previous studies is associated with the many millions of cases of wine produced in Napa County from non-
Napa grapes.
Winery and Vineyard Employment
For winery and vineyard employment, we based our estimates in both cases on US Department of Labor
Bureau of Labor Statistics estimates of employment by statistical category by county. Since these data
count only employees eligible for unemployment insurance, i.e., full-time employees, we have adjusted
these data to include owner-operators and contract workers.
These data do not differentiate between workers involved in processing Napa Valley grapes and those
involved in processing non-Napa Valley grapes and neither do the wineries in which they are employed.
The wine produced in Napa County from non-Napa Valley grapes is processed by many of the same
wineries which produce Napa Valley appellation wines, generally those wineries whose operating permits
predate the 1990 Napa County Winery Definition Ordinance requiring Napa County wineries to use a
minimum of 75% Napa County grown grapes.
Stonebridge Research: Economic Impact of Napa County’s Wine and Grapes, 2011! Page 17 of 19

18. Thus, winery employment data is comparable to that in the 2008 report, as is tourism data -- and both
reflect all winery activities in the county, whatever the grape source.
While some out-of-county contract labor is used for Napa Valley viticulture, most of Napa’s vineyard labor
today is employed locally. The previous study assumed a larger amount of contract labor, with a larger
share from out of county.
Grapes
The new report clearly differentiates between non-Napa-Valley and Napa Valley grapes.
Wine and Grape Value
Wine production estimates for the 2008 report would have been based on 2005 red wine grape production
(and 2006 Chardonnay and 2007 Sauvignon Blanc production) while the 2011 report is based on 2008 red
wine grape production (and 2009 Chardonnay and 2010 Sauvignon Blanc Production.) The red wine grape
crop in 2008 was only 60% of the size that in 2005. The wines made from the 2008 crop also came to
market in the much weaker 2011 market. We assume somewhat lower average prices -- about 15% lower
-- for 2011 sales, compared with those in 2006, which was near the peak of the pre-recession “bubble”.
Thus, the value of wine produced and of grape sales were much reduced in the new report.
Financing Revenues
Total financing revenues of more than $292 million were estimated in 2008 (for calendar 2006), or about 7%
of assessed asset values for wine and vineyard, and related properties in the county. This was probably an
overestimate but the best available at the time. This year industry bankers estimated total financing
revenues between $90 million and $135 million per year, assuming an average yield rate of 4.5%. Credit
outstanding has certainly been reduced, along with interest rates but the 2008 estimate for 2006 was
clearly an overestimate. We estimate $135 million in annual financing revenues for 2011 from Napa and
non-Napa sources.
Wine Sales in Napa County
The 2008 study assumed one-third of Napa Valley appellation wines sold through the trade were sold
within the State of California and 5% of that was sold in Napa County, given the guidance that many of
Napa Valley’s smaller and mid-size wineries do not have national distribution and thus their sales tended
to be California focused.
For 2011, we were finally able to get distributors to estimate wine sales in Napa County, which produced a
surprisingly small estimate of .56% of total California sales of these wines, or about one tenth of our
previous estimate. Napa is only 1.7% of California’s total population. We know that many of the smaller
wineries sold a much larger share of their wine both within the county and within the state. Thus, for Napa
appellation wines, we assumed a larger proportion of such sales than we assumed for the non-appellation
wines, which are more likely to have national distribution.

19. Replanting and Vineyard Development
The 2008 report covered the 2006 crop year, when non-bearing acres totaled 2948 acres, compared with
only 1855 non-bearing acres in 2011, which is reflected in the far higher estimate in the earlier report for
vineyard development costs.
Moreover, since 2006, a far larger share of vineyard labor in the county is employed full-time and vineyard
managers are more likely using their existing labor force for this work, rather than additional, possibly
contract labor. We do however assume a small amount of out-of-county contract labor for vineyard
development.
Overall, we assume about 5% of Napa Valley vineyards are replanted each year, at an average cost of
$30,000 per acre and about 4% of non-Napa vineyards replanted each year at an average cost of $20,000
per acre.
Public Revenues
Some public revenue data was available for the 2011 study that was not available in previous years,
particularly sales tax data directly paid by wineries and excise tax collected by the state from specifically
California producers.
